Answer 1

qn: A car travels with a speed of 50kmh in the 1st 30 minutes and 100kmh in the next 30 minutes. What is the total distance covered by the car?

ANS: 1st 30mins

speed of car= 50km/hr

time taken= 30mins= 1/2hr

distance travelled = speed×time

50×1/2

=25km

2nd 30mins

speed of car = 100km/hr

time taken = 1/2 hr (30mins)

distance travelled=speed× time

100×1/2

=50km

total distance travelled by car= distance travelled by car in 1st 30mins + distance travelled by car in 2nd 30mins

=50+25

=75km

the answer is 75km
